[Correspondence] A false aura of scientific controversy around salt?

The recent Article by Mente and colleagues1 (July 30, p 465), a pooled analysis of data from four prospective studies of more than 130 000 people on the link between sodium and cardiovascular events and death, found an association between low sodium intake (<3 g/day) and increased risk in individuals with and without hypertension; while high sodium intake (>6 g/day) was linked with added risk only in those with hypertension. The results raised questions about “whether public health policies targeted at reducing sodium in the entire population are appropriate”.
